Yeah, you caught me ;-)

Either making it optional or requiring a dummy value would work.
If a non-dummy value is given, we could use it to validate it.

But that would not be a useful application anyway.  So perhaps
just the sequence of "<type> SP <size> LF <contents> LF" would
be the most sensible thing to do.
